.. zephyr:code-sample:: ptp
|
|
:name: PTP
|
|
:relevant-api: ptp
|
|
|
|
Enable PTP support and monitor messages and events via logging.
|
|
|
|
Overview
|
|
********
|
|
|
|
The PTP sample application for Zephyr will enable PTP support.
|
|
|
|
The source code for this sample application can be found at:
|
|
:zephyr_file:`samples/net/ptp`.
|
|
|
|
Requirements
|
|
************
|
|
|
|
For generic host connectivity, that can be used for debugging purposes, see
|
|
:ref:`networking_with_native_sim` for details.
|
|
|
|
Building and Running
|
|
********************
|
|
|
|
A good way to run this sample is to run this PTP application inside
|
|
native_sim board as described in :ref:`networking_with_native_sim` or with
|
|
embedded device like Nucleo-H743-ZI, Nucleo-H745ZI-Q, Nucleo-F767ZI or
|
|
Nucleo-H563ZI. Note that PTP is only supported for
|
|
boards that have an Ethernet port and which has support for collecting
|
|
timestamps for sent and received Ethernet frames.
|
|
|
|
Follow these steps to build the PTP sample application:
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/net/ptp
|
|
:board: <board to use>
|
|
:goals: build
|
|
:compact:
|
|
|
|
Setting up Linux Host
|
|
=====================
|
|
|
|
By default PTP in Zephyr will not print any PTP debug messages to console.
|
|
One can enable debug prints by setting
|
|
:kconfig:option:`CONFIG_PTP_LOG_LEVEL_DBG` in the config file.
|
|
|
|
Get linuxptp project sources
|
|
|
|
.. code-block:: console
|
|
|
|
git clone git://git.code.sf.net/p/linuxptp/code
|
|
|
|
Compile the ``ptp4l`` daemon and start it like this:
|
|
|
|
.. code-block:: console
|
|
|
|
sudo ./ptp4l -4 -f -i zeth -m -q -l 6 -S
|
|
|
|
Compile Zephyr application.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/net/ptp
|
|
:board: native_sim
|
|
:goals: build
|
|
:compact:
|
|
|
|
When the Zephyr image is build, you can start it like this:
|
|
|
|
.. code-block:: console
|
|
|
|
build/zephyr/zephyr.exe -attach_uart
|
